Translation of betätigen

I have considered the option to bring my friends from other social networks and invite them to join here. They can develop better language skills here. I'd love to pursue that goal, but I want to write in English.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
I've never been to Switzerland, but I'd like to go to the Alps. Until now I was only in Austria and in France. Maybe I will go there, for example skiing in Davos or in another nice mountain village.
